SOLIDIFIED ALCOHOL AND PROCESS OF MAKING THE SAME.

Specification of Letters Patent.

Application filed December 7, 1908.

Serial NO. 166,371.

To all whom it may concern:

Be it known that we, VICTOR PERELZ- VEICH, chemist, a citizen of the Russian Empire, residing at Zurich, IV Clausiusstr. 38, in the Republic of Switzerland, and GUSTAV ROSENBUSOH, manufacturer, a citizen of the German Empire, residing at Zurich, IV Sonneggstr. 76, in the Republic of Switzerland, have invented new and useful Improvements in solidified Alcohol and Processes of Making the Same, of which the following is a specification.

Recently various-preparations and mixtures have been produced, which, added to alcohol, have the effect of solidifying the alcohol or of setting the same to a more or less hard mass. Some of these preparations or mixtures have the disadvantage, however, that they decrease the calorific value of the alcohol, while others, during the combustion of the mass, leave such large quantities of residue that the continuous burning of the mass is interfered with; other pre arations have a tendency to become lique ed when burning or else are liable to explosion when ignited.

We have now succeededin producing a stance is -a neutral fat which surpasses in many respects the stearin of commerce, the latter being much admixed with impurities consisting of the highermembers of the fatty acid series, and it has certainadvantages over all solidifying agents hitherto known. The tristearin is produced by heating glycerin and stearic -acid for a considerable time to a-high temperature, whereby at first monostearin and finally tristearin is formed, this being a neutral fat but not in its pure state being admixed with-fatty acids. The synthetical production of this com ound is described in Dr. Beilsteins Hand uch der. org. (I'hemie, 2nd edition, 1886, Hamburg, Leip- 'zig, I, p; 421;'also in Hollemann, Lehrbuch der org. Ohemie, Leipzig, 1899, p. 171.

, As an example of the manner in which our process is efieoted, we preferably use denatured alcohol and to a quantity of this liquid we add a mixture consisting of about/3% tristearin and about 5% sodium sebatr j the whole isthen heated for a short time. After the mixture has dissolved, an alcoholic ethereal solution of about 1% of tetra-nitrate of cellulose is added; after a short space of time the latter ingredient is dissolved and the whole mass assumes the solid state. The output of solid alcohol corresponds in quantity to the amount of liquid alcohol used at the beginning of the rocess. The solid mass thus produced, gives, when ignited, a flame ofintense heat; it melts very slowly, solidifies quickly, and leaves but little residue after ignition and at thesame time all danger of explosion is obviated. We may vary the proportions of the constituents of the solidifying agent without de arting from the principle of the invention. aving thus described our invention what we claim is:

1. The herein described process of produc ing solid alcohol, which consists in mixing alcoholrwith tristearin, sodium sebate, and tetra-nitrate of cellulose.

2. The herein described process for pro ducing solid alcohol, which consists in adding to denatured alcohol a solidifying agent formed of about 3% of tristearin, about 5% of sodium sebate,-and about 1% of tetranitrate of cellulose, substantially as described.

3. The herein described process of producing alcohol in the solid state,-which consists in adding to denatured alcohol about 3% of tristearin and about 5% of sodium sebate, heating the mixture so obtained and then adding to the dissolved mixture about 1% of tetra-nitrate of cellulose in alcoholic ethereal solution, substantially as described.

4. As an article of-manufacture, the herein described solid alcohol, consisting of a mixture of denatured alcohol, tristearin, sodium sebate and tetra-nitrate of cellulose, substantially as described.

5. As a new article of manufacture, the herein describedsolid alcohol, consisting of an alcoholic solution of about 3% tristearin, about 5% sodium sebate and about 1% tetra-nitrate of cellulose, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
